low ground clearance

I recently purchased a new F/S bike. I've owned plenty in the past and don't recall this as a common reoccuring problem. The end of my crankarm hits the ground what seems like an inordinate amount of times, every ride. i have adjusted my sag to the point I feel like I'm riding a hardtail. Even inflated my tires a little more. Also I use egg beater pedals, to increase clearance ratio. Lastly, I run a 175mm crankarm length, since I'm 6'1" and have a 34 1/2 inseam. If I run shorter crankarms will this make a differance and if I did change will I give up anything in performance, cadence, power, etc. Any other suggestions. Thanks for your help.

I can only assume this bike has a lower bb height than your previous bikes without more details. Have you changed terrain? Are you standing more? Different kind of shock or more travel with this bike? Details help...

I doubt 5mm of arm length, say if you go to a 170, is going to make a great difference in clearance as that's not much difference.

I riding the same terrain or the same trails, always in the saddle, with the same rear shock. Never pedals through turns (between 60 and 90 degrees). I have somehow lost BB clearance. It must be in the rear shock, in the sag while I'm riding. I missing something somewhere. Thanks for your replys and suggestions.

It's more likely just that your new bike has a different bb height (distance center of bb spindle to ground), they're not all created equal. I have one fs bike where pedal strike is significantly easier to do than the others, and it's not that the measurement is hugely different. Some shocks can blow through their stroke easier than others. What bike and shock is it?

Just check the difference in BB heights between the two bikes (load the FS when you measure). Lower BB bikes just require a modification to the way you pedal. The pedal strikes will be obvious at first but you'll adapt and won't get many/any pedal strikes after a while.
